CAR-WHEEL..

Specification of Letters Patent.

ratentecl May 1, 1906.

Application filed December 18,1905. Serial No. 292,175.

.T0 a/ZZ whom it ina/y concern:

Be it known that I, FRANK LATIMER, a citizen of the United States, residing in High Bridge, in the county of Hunterdon and State of New Jersey, have invented certain new and useful Improvements in Car-Wheels, of which the following is a specification.

The present invention relates to car or locomotive wheels, the object being to provide an improved car-wheel, the center and tirel of which are formedseparately, but so con nected that lateral play or movement of one part relatively to the other, which is a source of great trouble in wheels of this character, is entirely obviated.

A further object of the invention is the prosteel-tired wheel, the center of which, after the wearing down of the tire, can be readily re-tired and the tire of which is so locked to such center that should the tire inuse split circumferentially the arts would still be locked to the center o the wheel in such manner as to prevent accident, and in which the locking means engage the tire throughout a relatively great area thereof, so that there is little opportunity for shouldN the tire become broken, to fly away from the center.

In the drawings accompanying and forming a part of this specification, Figure 1 is a side view of this improved wheel, a part of the tire and center -being broken away to illustrate the mode of assembling the same. Fig. 2 is a cross-sectional view thereof. Figs. 3 and 4 illustrate portions, respectively, of the center and tire. Fig, 5 is a perspective view of the locking device or key which assists in locking the two parts together, and Fig. 6 is a sectional view of a portion of a wheel having a somewhat different form of construction from that illustrated in Figs. 1, 3, and 4.

Similar characters of reference designate corresponding parts in the different figures of the drawings.

This improved wheel comprises a center 2, formed of any suitable material, and a tire 3, likewise formed of any suitable material, usually steel, and which may be an ordinary rolled-steel tire, or otherwise formed as may be desired, and which center may have any of the various forms of construction which may be desired to give toit, according to the service j to which the wheel is to be put-that is to say, it may be of a web formation or a ribbed formation or a spoked formation. The parts in practice will usually be assembled by heating the tire to allow heat and permitting it to cool and shrink on the center.

For the purpose of connecting the tire and center together the tire is provided withla circumferential rib or projection 4 adj acent to one side thereof and on the opposite side with a series of projections or lugs 5, having locking ends 6, which in the present instance are shown as dovetailed.

The periphery of the center is provided with a series of locking members 7, shown of a relatively large area,preferably extending well across the periphery of such center, so that the ends 8 and 9 thereof will lie between and engage the peripheral rib 4 and the lugs or projections 5 of the tire when the parts are assembled in the manner hereinafter set forth. The sides or transverse faces 10 of these locking members conform to the ends of the. locking-lugs of the tire, and therefore in the present instance are shown with dovetailed sides, so that the center may be inserted laterally into position with relation to the tire and then shifted circumferentially, so that the locking-lugs of the tire overlap the ends of the locking members of the center,

which latter will thus, as stated, lie between the projections 5 and the circumferential rib 4 of such tire. In this position of the assembled parts the dovetailed ends of the lockinglugs of the tire are opposed to the dovetailed ends of the locking members of the centerthat is to say, the ends of the lugs of the tire taper toward the tread of the wheel, while the side faces of the center locking members taper toward the hub of such wheel, so that such tapered faces4 may be considered as opposing each other and in this position form transverse ways or openings for the locking members 11 For locking the two members together after they are assembled in the manner indicated a locking device 1 1, which may be a drop-forging, is provided. It is shown having its side walls or faces tapered in opposite directions, as at 12 and 13, to correspond with the opposing tapered portions, res ectively, of the tire-lugs 5 and center loc zing members 7. One of these locking members is inserted in each opening between a pair of lugs 5 of the tire and a pair of lugs 7 of the center, thus locking the one to the other in a manner that will be readily understood. Each locking device has a headed cap 20, so that it completely closes the opening formed between thecoperating lugs of the tire and center and project into the peripheral rib 4 of the tire, and for this purpose it may be formed in any suitable way. In the present instance each locking device is shown provided with a pair of projecting ends 14, eX- tending into openings 15, passing through such rib, and which projections 14 may be upset at the outer side of such rib or threaded for the reception of nuts.

The center is provided with a circumferential shoulder 16, which engages the inner face of the circumferential rib 4 of the tire when the parts are assembled, so that from the foregoing it will be seen that the center and tire are clamped together sidewise, as well as peripherally, by means of the locking members, which need not necessarily project beyond the two sides of the tire since the same may be circumferentially both sides to permit the upset ends of nuts 18 at one side and the heads 20 of such locking device at the other side to be located within the side faces of the tire.

In practice the locking-lugs 5 and circumferential rib of the tire may be laterally interlocked with the ends of the locking members 7 of the center, as illustrated, for instance, in Fig. 6, in which case, however, when the tire is shrunk on, it would be necessary to form the interlocking side portions so that the A are somewhat spread apart and then roll them into position after the tire has been shrunk on. Having thus described my invention, I claim- 1. A car-wheel comprisinga tire, and a center interlocked transversely by independent dovetailed interlocking means.

2. A car-wheel comprising a tire and a center interlocked transversely by opposing and independent dovetailed interlocking means.

3. A car-wheel comprising a tire and a center having dovetailed interlocking means, which when assembled by inserting the dovetailed members of the center between the dovetailed members of the tire and shifting one of said members relatively to the other are locked together and locking members located in the openings formed between said dovetailed interlocking devices for locking said center and tire together.

4. A car-wheel having a tire provided with a circumferential rib on one side and a series of locking-lugs on the other side, a center having a series of locking members adapted to interlock with the locking-lugs of the tire when the parts are being be shifted intermediate said locking-lugs and rib of the tire, and headed locking members located in the openings formed between the ribbed, as at 17, at

ber or members against assembled and tol va circumferential rib on one side and a series of locking-lugs on the other side, a center having a series of locking members adapted to interlock with the locking-lugs of the tire when the parts are being assembled and to be shifted intermediate said locking-lugs and rib of the tire, and headed locking members located in the opening formed between the locking lugs and members of the tire and center respectively for locking said parts together, and having a part projecting into the circumferential rib of the tire and clamped at the outer side thereof, the side faces of the locking-lugs of the tire and center being dovetailed and opposing each other when assembled, and said locking member having dovetailed portions corresponding to the dovetailed portions of said lugs and locking members of the tire and center.

6.
